螺旋ＣＴ扫描能获得肺部真正的容积资料，因此除以横断面显示气道、纵隔、肺野、肺血管及胸壁外，还可经过计算机后处理，以多种重建方法显示胸部结构。较常用的基本技术有（１）多平面重建（ｍｕｌｔｉｐｌａｎａｒｒｅｃｏｎｓｔｒｕｃｔｉｏｎｓＭＰＲ）包括曲面重建（ｃｕ Spiral CT scan can get the true volume of the lungs, so divided by the cross section of the airway, mediastinum, lung field, pulmonary vessels and chest wall, but also through computer processing, a variety of reconstruction methods to show the chest structure. The more commonly used basic techniques are (1) multiplanar reconstruction (MPR) including surface reconstruction (cu
